Q5: The rating definitionsA5: Ratings are based on ISO 8665 conditions of 10kPa (29.612 in Hg) and 25℃ (77℉) and 30% relative humidity. Propeller shaft power represents the net power available after typical gear losses and is 97% of rated power. Power rated in accordance with IMCI procedures.
Fuel consumption has a tolerance of +5% and is based on fuel of 35°API gravity at 16℃(60℉) having an LHV of 42,780 KJ/KG (18,390 BTU/lb) when used at 29℃ (85℉) and weighing 838.9g/liter (7.001lb/US gal) with LTA when available.

Q6: The definitions of continuous duty (CON)A6: Intended for continuous use in applications requiring uninterrupted service at full power, this rating is an ISO 3046 standard power rating.
Typical vessel applications include: ocean-going displacement hulls such as fishing trawlers, freighters, tugboats, bottom drag trawlers, and deep river towboats.

Q7: The definitions heavy duty (HD)A7: Intended for continuous use in variable load applications where full power is limited to 8 hours of every 10 hours of operation. Also, reduced power operations must be at or below 200rpm of the maximum rated rpm. This is an ISO 3046 Fuel Stop Power Rating and is for applications that operates 5,000 hours per year or less.
Typical applications include: displacement hull vessels such as mid-water trawlers, purse seiners, and towboats where frequent slowing is common and engine speed and load is stable. Also used in high speed vessels such as ferries and crewboats.
Typical auxiliary applications include: cargo pumps and thrusters in dynamic positioning modes.

Q8: The definitions of prime powerA8: A 10 percent overload capacity is available for a period of one hour within a twelve hour period of operation. Total operating time at 10 percent overload power shall not exceed 25 hours per year. This power rating conforms to ISO 8528 guidelines.
Engine with this ratings are available for an unlimited number of hours per year in variable load application. Variable load is not to exceed a 70 percent average of the rated power during any operating period of 250 hours. Total operating time at 100 percent prime power shall not exceed 500 hours per year.
